Radiation image read-out method and apparatus

摘要

A radiation image read out method and apparatus comprising stimulating a divalent europium activated cesium halide phosphor screen wherein said halide is at least one of chloride and bromide, that has been exposed to a radiation image, detecting light emitted by the phosphor screen (23) upon stimulation (25), erasing the phosphor screen by exposing it to erasing light emitted by an erasing light source (26) assembly having an electrical power not greater than S max x 1 Joule wherein S max is the maximum surface area of the stimulable phosphor screen read out in a read out apparatus.
